feat(app): the operator's overview of screens, grants to several people at once with one budget each, assistants by provider

Halkyon Learn's ADR 0021, D57 to D63, on halkyon_base's budgets and
effort:

- The operator's screen is an overview (Waiting, Operators, Accounts,
  Assistants, each with its count) whose rows open screens of their own,
  read 50 at a time as they scroll (OperatorListCubit, OperatorPage), so
  hundreds of accounts push nothing else down (D62).
- A handle is picked among the accounts there are (AccountSuggestionField):
  appointing an operator and granting take no other (D61).
- AssistantGrantsScreen replaces AssistantGrantsCard: the assistants set
  up by provider, with their efforts and prices; the people granted, found
  by their handle's start; one sheet granting several assistants, a
  provider's at once, to several people, each with one budget in money and
  tokens a day and a month, or changing one person's (D58, D59).
- Assistants are grouped by provider wherever they are listed, each under
  its name with a dot in its colour (ProviderLabel, D60).
- AssistantsCard shows what is left of the person's budget for all their
  assistants together; the months of the figures run oldest first (D57).
- AssistantChoice says the efforts a question may ask at and the ceiling
  on output each asks for (D63); a person's own key gets none and keeps
  4,096 tokens.
